FOLDING AND CUTTING COUPLE FOE FOLDING MACHINES.

Application filed Gctober 3, 1923, Serial N0. 638,365. Renewed May 2, 1928.

The principal objects of this invention are to provide each of the folding and cutting cylinders cast in a single piece, doing away with the removable bri lges ordinarily employed, and thus reducing the cost of manufacture and especially providing for the mounting of the movable parts without the necessity of machining the supporting and bearing surfaces so that the cylinders and the detachable parts and their connecting means are all formed of castings without finishing. Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is an end view of the folding and cutting cylinders of a folding machine showing interior construction in accordance with this invention;

Fig. 2 is a plan of the cutting and folding couple;

Fig. 3 is a sectional view of the same on the line 8-3 of Fig. 2 with the movable and detachable parts omitted, that is, it is a sectional view of the two castings as they are cast and provided with seats for receiving the parts that are to be attached to them;

Fig 4 is a sectional view of a portion of the folding cylinder showing the folding blade turned to a position to be introduced or removed;

Fig. 5 is an enlarged view of one of the pin holders and its guide; and

Figs. 6 and 7 are sectional views of two forms of cylinders.

The cutting and folding cylinders'used in folding machines are made ordinarily of which the expense of providing these featuresis very largely eliminated.

Referring first to the folding cylinder 10, this is cast in a single piece as shown in Fig. 6 or on a shaft as shown in Fig. 7. In either case it is cast under size and afterwards an outer layer 9 of soft metal is cast on it with its outer surfaces finished in the act of castlng. The journals also have their outer surfaces 8 finished in the same way. The cylinder is provided in the casting operation with openings 11 extending all the way through for the purpose of reducing the weight of the casting. It is also provided with two opposite passages13 extending outwardly toward the circumference for receiving a pair of opposite blocks 14 for holding the soft pads to receive the edges of the cutting blades on the cutting cylinder.

The folding cylinder is provided with openings 12 located diametrically opposite each other, extending nearly all the way through the cylinder from one end to a solid integral wall at the other, each provided at points at opposite sides of the openings 12 and at its open end with a flat surface having two seats 15 of soft metal alloy capable of setting quickly without material shrinkage and thus capable of being finished in the molds in which it is cast. These seats are cast directly on the rough surfaces of the cylinder, which is cast with depressions for receiving them. They are finished on their outer surfaces in the act of casting. They are held in position in any desired way, but they are permanently mounted on the cylinder. Each pair of these seats receives a bracket 16 which brackets are provided with perforations. In line with these perforations are similar ones in the opposite end wall of the cylinder. These perforations are provided with soft metal bearings i7 and 48 per manently cast in posit-ion and finished interiorly in the act of casting. They carry the impaling pin shaft1'7. This shaft has a crank 18 provided with a cam roller 19 adapted to be oscillated by a cam of the usual kind, not shown. Each shaft 17 also has arms 20 each pivotally connected with the end of a pin holder 21, the latter being screwed into an oscillatingly mounted stud 22 in the arm 20. This pin holder is provided with an impaling pin 28 for the usual purpose.

The impaling pin is guided in a cylindrical stud or guide 24 which is fixed in position in a body of soft metal alloy 25 such as that described above, and cast in a cylindrical opening in the casting 10. This soft metal seat is provided with projecting surfaces on iii) two sides at ri ht angles to each other for the purpose of supporting the blocks 14. This soft metal seat is cast permanently in position in the cylinder and provided with finished cast surfaces for supporting the block and the guide 9A. The pin holder 21 passes through this guide and out to the circumference of the cylinder where it operates in the usual manner.

Also located at diametrically opposite sides of the cylinder are two longitudinal openings 26. These openings do not extend all the way through the cylinder. There is a wall at one end so that that end of. the cylinder is not perforated at these points, but at the other end the opening extends all the way through;

These openings 26 are interrupted at intervals by a series of bridges 27 extending across them and formed integrally in the act of casting the cylinder 10. These bridges are continuous with the exterior surface of the cylinder and perform the same function as the ordinary removable bridges, but obviously do not require any, machining inside. These openings 26. are cylindrical in cross section and have soft metal seats 28 cast in position at tneir open ends in -the manner above described to permit of the mounting of brackets 29 therein. These brackets 29 have soft metal bearings 31 cast in finished form for a folding blade shaft 30. The other end of each shaft is carried in a similar bearing 31 in the opposite end wall. These two bearings 31 are carefully cast in alignment with their inner surfaces finished in the cast ing operation. Two of these shafts extend along the roll in the usual way through these openings and are provided with the usual folding blades 32 acting to tuck the folded product between the folding rolls. These blades project through the spaces between the bridges as usual. The shafts are provided with gears 38 to be operated by the usual gears and timed to rotate as usual. The openings 26 between the bridges 27 are curved substantially on a semi-circle to give room for the blades 32 to swing in them. Under the bridges the openings 46 are of triangular shape to allow the folding blades and shafts to be inserted. The soft metal surfaces 9 and 25 can be integral with each other if desired.

In the assembly of these parts the brackets 29 are placed on the folding shaft '30 and both inserted endwise from the open end of the cylinder with the folding blade located in the position shown in Fig. l so that it can be inserted in the triangular openings. Likewise if there is any necessity of removing them they can be taken out in the same way.

The cutting cylinder 35 is constructed on the same principle as the folding cylinder. It has the usual knife 36 and impaling pins 37 operating in guides 38 and moved by arms 39 on a longitudinal shaft 40. This cylinder is cast with an opening 41 all the way across it for this shaft and is provided with fiat surfaces d2 having soft metal seats 43 cast thereon for brackets 44 for mounting this shaft. The guides 38 are mounted in soft metal seats l5 for the same purpose as in the folding cylinder. An external layer 49 of soft metal like the layer 9 is also shown for the same purpose. The cutting cylinder being more simple than the folding cylinder no further description of the details need be given.

In this way it will be seen that these cylinders can each be formed from a single piece of cast iron with a minimum of weight and in such a way that no machining of the cylinder is necessary. The soft metal seats and surfaces can be put on by the application of suitable molds. The work is simple and re quires very little skilled labor with the exception of n'iakingthe' molds for the soft metal. The parts are accurately located in position, the soft metal seats are permanent, the detachable parts can be inserted in the manner described in a very convenient way, and the whole device can be set up and gotten into working shape without setting the cylinder up in a lathe or other machine tooling.

Although I have illustrated and described only a single form of the invention as applied to the folding cylinder and a single form as applied to the cutting cylinder 1 am aware of thefact that other modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in thclaims.
